Social isolation, psychological health, and protective factors in adolescence

This study investigates the relationships among social isolation, psychological health, and protective factors in adolescents. Feelings of social isolation may influence psychological health in adolescents, but protective factors such as family connectedness, school connectedness, and academic achievement may also play a key role. The sample included 4,746 adolescents from 31 middle and high schools. Participants responded to 221 survey questions regarding peer relationships, psychological health, school connectedness, family relationships, and academic achievement. The findings revealed that social isolation was associated with an increased risk for depressive symptoms, suicide attempts, and low self-esteem. Protective factors influenced associations between social isolation and psychological health. Implications for prevention such as building healthy peer relationships, promoting family connectedness, and developing school-based interventions are discussed.     

The role of emotional elaboration in the creation of false memories

Two experiments employed an eyewitness suggestibility paradigm to examine the effects of emotional elaboration on the creation of false memories for suggested events. The results of both experiments converge in showing that reflectively elaborating on the emotional consequences of suggested events increases both false belief and false memory in having witnessed the suggested events. Moreover, the results also showed that emotional elaboration leads to higher false memory than other types of meaningful elaboration, thus providing evidence that the emotional content of the elaboration plays a role in promoting false memory development. The results have several real‐world implications for forensic and therapeutic interviews. Copyright © 2008 John Wiley & Sons, Ltd.     

Construct Validity of the Perceived Criticism Measure

The construct validity of the Perceived Criticism Measure (PCM) was examined in 2 studies. In Study 1, 50 community couples participated in problem-solving interactions after which they rated interaction-specific perceived criticism and their criticism of their spouses. In addition, they provided ratings of perceived criticism for their relationship overall and completed measures of psychopathology and marital satisfaction. For both husbands and wives, convergent validity was demonstrated by moderate-to-large correlations between the PCM and spouses' own ratings of their criticism for both general and interaction-specific perceived criticism. In Study 2, 37 patients with obsessive-compulsive disorder and their spouses participated in problem-solving interactions and provided ratings of marital satisfaction and general perceived criticism. Five untrained coders rated the interactions according to their own definitions of the relatives' destructive criticism of the patient. Their aggregated ratings proved strongly related to patients' PCM scores. Higher PCM scores were related to lower marital satisfaction in both Studies 1 and 2. The results of these studies are supportive of the convergent validity of the Perceived Criticism Measure. Evidence of discriminant validity was mixed.     

The aftermath of 9/11: effect of intensity and recency of trauma on outcome

Does trauma exposure have a long-term impact on the brain and behavior of healthy individuals? The authors used functional magnetic resonance imaging to assess the impact of proximity to the disaster of September 11, 2001, on amygdala function in 22 healthy adults. More than three years after the terrorist attacks, bilateral amygdala activity in response to viewing fearful faces compared to calm ones was higher in people who were within 1.5 miles of the World Trade Center on 9/11, relative to those who were living more than 200 miles away (all were living in the New York metropolitan area at time of scan). This activity mediated the relationship between group status and current symptoms of posttraumatic stress disorder. In turn, the effect of group status on both amygdala activation (fearful vs. calm faces) and current symptoms was statistically explained by time since worst trauma in lifetime and intensity of worst trauma, as indicated by reported symptoms at time of the trauma. These data are consistent with a model of heightened amygdala reactivity following high-intensity trauma exposure, with relatively slow recovery.     

Thwarting the Need to Belong: Understanding the Interpersonal and Inner Effects of Social Exclusion

The need to belong is a powerful motivational basis for interpersonal behavior, and it is thwarted by social exclusion and rejection. Laboratory work has uncovered a destructive set of consequences of being socially excluded, such as increased aggressiveness and reduced helpfulness toward new targets. Rejected persons do, however, exhibit a cautious interest in finding new friends. Theory and intuition associate social exclusion with emotional distress, but laboratory research finds instead that the first response is a reduced sensitivity to pain and an emotional insensitivity that hampers empathy and may contribute to a variety of interpersonal behaviors. Self-regulation and intelligent thought are also impaired as a direct result of being rejected.     

Body dissatisfaction and body comparison with media images in males and females

This study examined the role of media body comparison as a mediator of the relationships between psychological factors and sociocultural pressures to be thin and body dissatisfaction in both females and males. Participants were 1,386 females (mean age = 19.37 years) and 1,130 males (mean age = 19.46) from diverse backgrounds who completed a self-report questionnaire. Path analysis was used to test a cross-sectional model in which media body comparison mediated the impact of self-esteem, depressive mood, parent dieting environment, friend dieting, TV exposure, magazine message exposure, weight teasing and body mass index (BMI) on body dissatisfaction. In females, media body comparison partially or fully mediated relationships between self-esteem, depressive mood, friend dieting, magazine message exposure and BMI, and body dissatisfaction. In males, media body comparison was not a significant predictor of body dissatisfaction. This research particularly highlights the need to further examine processes that are involved in the development of body dissatisfaction in males.     

Human search procedures and the use of expert systems

Four experiments are reported. These experiments compare the effects of two different forms of machine advice on performance on a complex search task. The task involves determining which of a set of factories is responsible for polluting a river by testing the river for the presence or absence of various pollutants. Subjects either receive a suggestion as to which pollutant they should test for on each go, or following testing for a pollutant they are told which of the factories could possibly be polluting the river at that stage, or they receive a combination of the two forms of advice. The experiments show that suggesting to subjects which pollutant they should test for on each go is of no benefit, whereas providing a list of possible factory names after testing for each pollutant significantly benefits performance. Only subjects who receive both types of advice simultaneously, however, maintain an improved performance level when the advice is withdrawn. This research was supported by the Alvey Directorate. Mr. E.C. Portman of ICL, West Gorton, acted as “industrial uncle” to the project.     

Brand character as a function of brand loyalty

This study investigated the relationship between self-image, brand image, and brand loyalty by asking whether people use products to enhance self-image. Subjects described themselves on an adjective checklist, then listed product brands to which they consider themselves loyal or not loyal. One month later, using the same adjective checklist, subjects described the type of person who would buy a particular brand to which they are loyal and a brand to which they are not loyal for both gender and non-gender related products. Significant differences between the two groups and a high correlation between self and product user ratings, were found.
